Pipe cap



FIG. 1 is a perspective view of a pipe cap, showing my new design;

FIG. 2 is a front elevational view thereof, the rear elevational view, left-side elevational view, and right-side elevational view all being a mirror image thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a top plan view thereof; and,

FIG. 5 is a cross-sectional view thereof, taken generally along lines 5-5 of FIG. 3.

The cut lines in FIGS. 1, 2 and 5 show that the design has an indeterminate height. 

I claim the ornamental design for a pipe cap, as shown and described.
